Goodyear Eagle F1 Asymmetric 5 vs Bridgestone Potenza Sport: A data was formulated using both these tires on the same car to observe how they act under various situations.
The Goodyear Eagle F1 Asymmetric 5 is a High Performance Tire which came before the Asymmetric 6. Some amazing numbers were seen with this tire especially when it comes to wet road traction.
Examine the treads on these tires closely. They hold the key to knowing which to choose. In fact if you visit my "tread design" page, picking the right tire would never bother you.
On the other hand, the Bridgestone Potenza Sport is another UHP. It has been among the top-ranking tires of 2021. The tire also showed remarkable traction on both dry and wet asphalts. But you get a lot of road noise.
Let’s see how these tires performed side by side.

Side by Side Comparison
Goodyear Eagle F1 Asymmetric 5
Bridgestone Potenza Sport
Traction on dry roads:
Vs
It can be seen clearly that the Potenza sport looks more aggressive on it’s shoulders. There are also more sipes on the tire. But they have less depth when compared to Asymmetric 5.
The tire ribs run continually over the circumference which provides a better contact patch to hold on the dry surface. In other words, there are no blocks in the middle.
So, overall, Potenza Sport offers more contact patch with the road which translates in to a better grip.
Statistically speaking, the Bridgestone Potenza Sport has a dry handling average lap time of 94 seconds. And decelerating from 60 mph, it has a dry braking distance of only 109 feet. For Assymmetric 5, the tire covered the laps in 96 seconds, while the dry braking distance was found to be mere 112 feet when decelerating from 60 mph.
| Potenza Sport | Asymmetric 5 | |
| Dry Braking Distance | 109 feet | 112.4 feet |
| Dry Handling (Avg lap time) | 94.3 seconds | 96 seconds |
FYI: The Goodyear SuperSport did the laps even better. And Michelin Pilot Sport 4s was the best in dry braking.
As you can see, the difference is not too much. So Asymmetric 5 still has a pretty good traction as well.
The Eagle F1 Asymmetric 5 is composed of a highly refined silica compound that works to amplify the grip of the tire, ultimately resulting in a shorter braking distance and exemplary drag on both wet and dry surfaces alike.
The tire’s asymmetric tread pattern and stiff and rigid framework result in responsive and sporty handling, particularly on dry road surfaces.
Whether it be the composition or the tread design, everything in this tire has been chosen to offer quality traction and control at high speeds and sharp turns.
So what do we know from these tests?
When it came to dry handling, it was an extremely close call between the two tires at hand. Since the difference is only minimal for dry handling, other factors should be considered before making a decision.
Overall speaking, if you have a sports car, you will most likely find the Bridgestone Potenza Sport to be the choice for you as the dry traction of this tire is simply awesome.
Wet On Road Traction
When it comes to wet traction, both tires performed equally as good. The sipes on Potenza are more, but the deep cuts seen on Assymmetric 5 wipe away water equally as better.
Following are the test figures.
| Potenza Sport | Asymmetric 5 | |
| Wet Braking Distance | 114 feet | 110.6 feet |
| Wet Handling (Avg lap time) | 64.5 sec | 65.2 sec |
Rolling Resistance
The Goodyear Eagle F1 Asymmetric 5 has a reduced rolling resistance, all thanks to the combinations of materials introduced in it such as natural and synthetic rubber (refined silica), designing stiffer sidewalls, and reducing tread depth. Each of ‘these green innovations’ helps reduce tire deformation, which in turn results in a lot of pennies saved in the name of fuel.
On the paper, the tire has an impressive rolling resistance value of 8.9 kgt. Compared to the Bridgestone Potenza Sport’ s 9.5 kgt. (less is better)
The high rolling resistance of Potenza is because of the tire’s more contact with the road.
This high rolling resistance comes at the expense of fueling costs and can amount to major expenses over the course of time. Aside from this, it is not environment friendly and can also impact your tyre life and result in more noise.
Aquaplaning/Hydroplaning
The Goodyear Eagle F1 Asymmetric 5 has pretty good resistance to aquaplaning due to its asymmetrical tread design and contact patch extension feature. The tyre is able to offer good control and grip in wet conditions at high speed, making it an ideal choice for rainy seasons.
The tread depth and design of Eagle F1 make it easier to channel the water while maintaining the speed without the risk of slippage.
The inboard All-Season Zone helps push water away from the tread for enhanced all-season traction in rain and light snow while allowing additional biting edges to generate more traction.
The Goodyear Eagle has a float speed of 48 mph. For Potenza Sport its lower, 45.6 mph. So Asymmetric 5 is better here.
However, the difference is negligible.
Noise and comfort
The Goodyear Eagle F1 Asymmetric 5 has a very good noise reduction performance which makes your rides quite worthwhile. The tire has SoundComfort Technology, which involves the manufacturer adhering a layer of sound-absorbing foam to the inner liner of the tire to reduce cabin noise in the vehicle.
The dampening of the sound results in a quiet and pleasant journey for the driver.
The external noise is recorded to be 71.1 dB the Goodyear Eagle F1 Asymmetric 5. For Bridgestone Potenza, its a little higher, 71.7dB.
For the Bridgestone Potenza Sports, there are a number of reasons for its high noise level. Its high rolling resistance produces more friction and therefore more noise. Its broad, sporty shape is also a factor contributing to noise as it increases the contact area.
Designed for stability at high speeds and excellent traction, these driving conditions can also greatly contribute to the noise.
Tread wear
The Goodyear Eagle F1 Asymmetric 5 is a great all-season tire with a 45 000 miles warranty.
This exemplary warranty reflects the superior quality tread wear of the tire.
Other than being equipped with a rigid frame, the tire’s internal structure features twin steel belts reinforced by spirally wrapped poly-amide cord cap plies to blend high-performance handling and control with high-speed durability.
The excellent tread wear rating of around 300 is a result of the tire’s rubber composition, as well as its advanced engineering design. The tread design not only offers excellent grip on the road but is also long-lasting.
The Bridgestone Potenza Sports on the other hand has a tread wear warranty of up to 60,000 miles.
Both tires have however, the same life, with Potenza wearing off slightly quicker, because it has more contact patch with the road.
The tread pattern geometry of the tire maximizes rubber to road contact therefore increasing contact pressure. The more the contact with road, the quicker a tread tends to wear.
Another Budget Pick: Altenzo Sports Comforter.
